Sesame crashes on Table view close

I have run into a problem on the database that I am programing. When ever I exit the table view Sesame crashes and  locks the database file. This happens on any database in the application that has records to view. It happen no matter which way you close (Esc, Ctrl-C, or click on the x)

I had not tried table view before this, but I wanted quick way to check for blank records that may have been entered.

One thing I have noticed is that the items in the table view are all greyed out.

I have tried it with the sample applications and can not get it to crash Sesame.

I am running Linux (Linspire 5.0).

Any ideas you can give me as to where to start to trouble shoot thins would be great.

Thanks!

You had a similar problem with a different window and you were looking into your mouse/video driver. You were also locking-up / crashing when opening up the Linspire's configuration manager. Did anything ever come of that?

I will look into the log files when I go home. I did look around last night on the Laptop. It has the same setup for graphics as the desktop. When I  tried to open the control panel to look at the mouse setting on the laptop the control panel application crashed. Not just once but every time. I smell a rat (or mouse)!


On a similar subject: which desktop manager are you running (Gnome? KDE?, etc?) I run Gnome on my desktop at Hammer and I run KDE on my development machine (this one) at home.

Hello Frederick,

If the sample applications are not causing it then it may be something in your Sesame file. Send them to support@Lantica.com Be sure to include a valid login if the application has security, the name of the form that you are opening table view on, and any other instructions that Technical Support would need to see this problem.

Mark, I have not had time to deal with the laptop problem.  I am doing my delevopment all on the desktop now and have been quite busy. I belive that Linspire uses the KDE desktop or some part of it as I have seen the KDE help at times when needing information.

Ray, I sent the datbase off so it can be looked at.

I also discovered that the problem doses not happen with all the forms in the application. Some did not have records so, I could not pull up the table view. Since then I have added records to them and entered table view and exited with no problem. There are only two forms that the problem displays itself with.

Hi Mark!
I trying to trouble shoot this problem I am wondering if again I do not have the need libraries installed. Is this list below the same for version 1.1.3 or have there been changes?

The shared libraries needed by Sesame 1.0.4 on Linux are:

libXext.so.6
libxml.so.1
libm.so.6
libpthread.so.0
libc.so.6
libz.so.1
libdl.so.2
/lib/ld-linux.so.2

Most Linux distros will automatically install all of these libraries. Some may make libxml, libz, and libXext optional. Libxml is the older XML library. Libz is a data compression library used (in Sesame) for images. and LibXext is a set of X11 (user interface) extensions.

Most of these .so files are required of any Linux executable, even system commands like ls, cd, and mv.

I just checked through the list and I have all the listed libraries. I just went into the designer file for my database in Sdesigner and then clicked the preview application and then tried the table view there, it crashed Sdesigner.

If it is not happening in every application, I would look into what makes that application different from others - as I am sure Ray is doing.

Hello Frederick,

The UserID element on the UserInformation form and the ProgramName and ShortForm elements on the ProgramInformation form have a restriction of just '!'. You will want to change this to '!/=', without the quotes.

Hi Ray!

Does changing the restriction fix the crash problem?

Can you explain the "why" of the change from "!" to "!/="?

The manual (Version 1.1) says that if you want a restriction of "Entry required" that it is "!" (In fact I see this restriction in screen shots in the manual.)

"/=" is a restriction of "Entry requested"

So what does "!/=" do?

What I want is that the user fills in the field and that it is not left blank.

I do not mind you saying that I need to change it but I want to know why, so I can learn from it as well.

Thanks for your help!

Hello Frederick,

Yes this will take care of the crash I do believe.

Why the change? To take care of this problem.

'!' means Mandatory
'/' means Not
'=' means Blank or Empty

So '!/=' means it is Mandatory that this element is Not Blank or Empty.

The manual is correct though - it is the program that is wrong. Using just a "!" in a restriction should recult in the same condition as "/=" being mandatory. It was in the code that translates the single"!" into the restriction "/=" and sets the mandatory flag - that the bugs was found.

Fixed. The fix will be in the next release.

BTW: nothing to do with Linux versus WIndows.
